List down your reasons

Take a piece of paper or pull out your phone's note pad, list down the task you need to do (make it specific) and list down three reasons why you need to do it (focus on what progress you will make rather than any negative reasons) 

Example:

Task: I need to study 3 chapters today

Reasons

1) I want to be a straight-A student

2) Studying now will save me from panicking last minute

3) I want to learn more about the topic
